Answer:
y=7 and x=-8
Step-by-step explanation:
Isolate x in the first equation:
10x=-17-9y
x=(-17-9y)/10
Substitute into the second equation:
7*((-17-9y)/`10)+10y=14
-119/10+37y/10=14
-119+37y=140
37y=259
y=7
Putting this into the first equation, we get that x=-8
Answer:
d
Step-by-step explanation:
Answer:
d =7.83
Step-by-step explanation:
d+(−5.004)=2.826
Add 5.004 to each side to isolate d
d+(−5.004)+ 5.004=2.826+5.004
d =7.83
